Euskelosaurus was a prosauropod giant. Unfortunately, we do not have a complete skeleton-only limb bones and vertebrae. Thomas H. Huxley named it in 1866-its name means "true-limbed reptile."

Euskelosaurus had huge limbs. The length of the limbs, their massive build, and the size of the dinosaur support the idea that Euskelosaurus was among the most sauropodlike of the prosauropods. It was a massive animal that walked on all four legs (quadrapedal).

Its femur (the thigh bone) had a twisted shaft. Jacques van Heerden suggested that this twisting meant that the back legs of Euskelosaurus were "bow-legged." If van Heerden is correct, this would be unusual for a dinosaur. All other dinosaurs' thighs were directly under their bodies.

The habits of Euskelosaurus remain a mystery, because the head, hands, and feet are unknown. Based on the parts of the skeleton we have, it appears to have been a large, slow-moving plant-eater somewhat similar to Apatosaurus. However, we will not know for sure until scientists find better fossils of this dinosaur.
